**Question 3 of 14****Compare, at the same temperature and pressure, equal volumes of H₂ and O₂ as to the following:****(a) Number of Molecules**- According to [Dropdown Menu], equal volumes of H₂ and O₂ at the same T and P have [Dropdown Menu] molecules.**(b) Mass**- mass O₂ = [Text Box] times mass of H₂**(c) Number of Moles**- According to [Dropdown Menu], equal volumes of H₂ and O₂ at the same T and P have [Dropdown Menu] moles. ### Understanding Molecular Properties#### (d) Average Kinetic Energy of the MoleculesIn this section, we compare the average kinetic energy of different gases.- **Formula (Input Field)**: Average kinetic energy of \( \text{O}_2 \) [compared to] average kinetic energy of \( \text{H}_2 \).#### (e) Rate of EffusionEffusion is the process by which gas molecules escape through a small hole.- **Input Field**: Rate of \( \text{H}_2 \) is [blank] times the rate of \( \text{O}_2 \).#### (f) DensityDensity is a measure of mass per unit volume.- **Input Field**: Density of \( \text{O}_2 \) is [blank] times the density of \( \text{H}_2 \).### Further Exploration- **Kinetic energy** is directly related to the temperature of the gas and is the same for all gases at the same temperature.- **Effusion rate** can be explored using Graham’s law, which relates the rates of effusion to the masses of the gases.- **Density** can be calculated using the ideal gas law and comparing molar masses.This activity helps build a foundational understanding of gas behavior and molecular comparisons in chemistry.
